VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 239,067, dated March 22, 1881.

Application filed July 24, 1880. (Model.)

To all whom it 'may concern:

Be it known that I, FRANCIS H. SHEPHERD, of Davenport, in the county ot' Scott and State of Iowa, have invented a new and valuable Improvementin Vapor-Burners; and Ido hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making apart of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation ot' a vertical central section of my improved vapor-burner, and Fig. 2 is a detail perspective view. This invention has relation to improvements in burners for illuminating purposes, wherein the vapors of hydrocarbon oils are used.

The object of the invention is to produce the vaporizatio'n of the oil and the conversion ot' the same into gas by the direct action of the illuminating-flame.

The nature ot' the invention consists in a heater-plate arranged in a direct line with the oil-induct passage, and provided with a burnertip designed to heat said plate, in combination with an induct-pipe filled with coke packing,

a vaporizing-chamber, and regulating-screw, all as hereinafter more fully shown and described.

In the annexed drawings, the letter A designates the L shaped body of my improved burner, having in its vertical branch a a mixing-chamber, F, and a generating-chamber, b, and in its horizontal branch a' a passage, c, communicating with the upper end ofthe chamber b by means of a reduced throat, d. It has also at its upper end a circular metallic disk, e, which, if desired, may be slightly concave on its upper face, into which is screwed or otherwise secured a burner-tip, f. As indicated in the figure, the tip j' has formed in it, directly under the slit i', a small perforation, i, in line with the upper surface of the disk'c, and the horizontal brauche' is extended across the under side of plate c, forming a part thereof, the object being, by means of the perforation fi, to direct a blaze in line with the surface of the disk and over the feed-pipe, so that it will heat the fluid as it passes from the main stem. The vertical branch a is tubular and open at its lower end, and is provided with a removable interior centrally-perforated collar, h, with which the conically-pointed end j of an adjusty ing-screw, S, engages. This screw engages a thread, 7c, at the lower` end of the branch a, and it establishes, cuts off, and regulates the communica-tion between the generating-chamber b and the mixing-chamber F by Ineans of the connection l between these chambers being below the collar h. Extending through the walls of the chamber F are the perforatons i, which admit air into the said chamber, which, commingling with the gas, which is very rich in carbon, produces a white dame and prevents undue smoking.

It will be observed that the passage c of branch a and the upper ends of the chamber b are directly under the heater-plate and in contact therewith. Consequentlyy the oil vaportain a supply of oil, which being lighted speedilyheats chambers F and b and the plate c, so that when oil is turned on gas is readily produced therein, and may be lighted atthe tip f. This is only requisite when the burner is first lighted, as the illuminating-flame, when once started, sufficiently heats plate c to produce an abundant supply of gas.

The oil in the cup G may be let into it by means of a stop-cock, n, in the bottom of chamber b, and the heavy residuum, which does not readily vaporize, if any should collect, is drawn off through a cock, fn', or other equivalent device.

The body of the burner, with its chambers F b and passage c, is cast in one piece with the disk e.

Oil is fed to the burner through a pipe, N, containing a crushed-coke lling, and leading to an elevated reservoir. The perforation i should be as near as possible to the bottom of the slit in the tip, and be partly covered by the heating-disk.

I am aware that burners have been made with inlet-pipes communicating with the central vaporizing-pipe and heating-disks above, but not in contact with the same, andI do not claim such devices, my invention having the heating-disk and inlet-pipe in contact, and having a heating jethole in the burner level with the disk and in the direction of the inlet-pipe in connection with other features, as claimed below.

What I claim as new, and desire to secure by Letters Patent, is-

l. In aburner for the vapors of hydrocarbon and other oils, the L-shaped burner-body, having the vertical mixing and generating chambers F b and thev horizontal passage c, leading into the upper end of the latter, the connection l between said chambers, the collar hin chamber Fabove said connection, the regulating-screw S,theheatingdisk @,the slit burner or tip f, having perforation i in line with said disk and below the slit, the air-holes i in chamber F, and the supply-pipe N, illed with crushed coke, all combined and arranged to operate substantially as specified.

2. The hydrocarbon-vapor burner having the heating-disk e, covering the induct c, the generating-chamber b, the slit tip f, and perforation i in said tip in line with the upper surface of the plate or disk e, andt he induct c below the slit in the tip, substantially as specied.

In testimony that I claim the above I have hereunto subscribed my name in the presence ot' two witnesses.
